[Amps] Chimney for GS-31B

[robert briggs]

Hi all,

I have been pondering for a solution for a chimney for various external 
anode tubes.I am currently completing another amplifier using a 
GS-31B.Not having access to Teflon or other expensive materials nor the 
finance to afford same I hit upon the idea of using some silicon baking 
sheet.I know the idea isn't new and I am wondering how many of you have 
actually tried it or at least thought about it.,I thought I would cut a 
strip of this material to make the cylinder and fasten it by "sewing" it 
up the join with a finer strip..Guess there is no other way of 
efficiently joining this stuff..However I will try this method tomorrow 
and let you all know how it goes..

I would be interested to hear any other suggestions.My research so far 
rules out poly tubing for chimneys..
